Google Software Engineer New Grad interview questions

First, I got an email from the recruiter that my profile was selected for the phone interview. The email was very lengthy and included loads of information such as job details, interview availability section, materials to prepare. then I provided my availability for the phone interview and got confirmation regarding the interview. Interview day- I was asked about my one of the projects and only one coding question. When I was solving that question, the interviewer was busy doing something else and was just listening to me. I thought Google interviews were interaction based but mine experience was a bit different. I was not able to complete the problem( probably lack of practice and stressed out). After 2 days, I got a call from the recruiter(not selected). The interview process was well managed and the recruiter was very responsive. Tip for the interview- Just go through basic data structures and algorithms.
